AceWiki-GF combines AceWiki with Grammatical Framework (GF) in order to make CNL-based semantic wikis multilingual.

The content languages of the wikis are defined by multilingual GF grammars. Each wiki article is stored in a language-neutral format but is viewable and editable via any of the languages supported by the grammar. The source of the grammar is integrated into the wiki and editable by the users.

The following screencast demonstrates the main features of AceWiki-GF using a geography wiki that is based on a multilingual version of Attempto Controlled English (ACE). The syntax of a large subset of ACE has been implemented in GF and ported to many languages using the GF Resource Grammar Library, resulting in the multilingual ACE-in-GF grammar. The ACE-based wikis offer automatic semantic consistency checking and question answering based on OWL reasoning via the meaning-preserving mapping from ACE to OWL.

You can download the screencast in the following formats: webm, mp4.
